Answer:

288

Step-by-step explanation:

If you didnt know a triangle has the area of a square/2

so basically what im saying is the area of that square/2 equals the area of the triangle

to find the area of the square you take 24 and square it

24^2=576

finally we divide that by 2

576/2=288

so the area of the triangle is 288

have a great day :D

The central angle of an arc measures 120° The radius of the circle measures 3 cm what is the area of the sector to the nearest h
jeka57 [31]

Answer:

The area of the sector should be 9.42cm^2 .

Step-by-step explanation:

-The formula for finding the area of a sector:

A = \frac{Arc}{360} \pi r^2

-Next use the arc measure and the radius in order to solve and get the answer:

A = \frac{120\textdegree}{360\textdegree}\pi 3^2

-Solve:

A = \frac{120\textdegree}{360\textdegree}\pi 3^2

A = \frac{120\textdegree}{360\textdegree}\pi \times3^2

A = \frac{1}{3} \pi \times 3^2

A = \frac{1}{3} \pi \times 9

A = 3\pi \approx 9.424

-Round to the nearest hundredth:

A \approx 9.42
